Scouting USA Baseball draft prospects

I spent two days in sweltering Durham, N.C. watching the start of USA Baseball's annual Prospect Classic, in which the collegiate national team and the trial roster for the 18U team are jumbled up on two rosters and play a pair of exhibition games, followed by two more exhibition games with their normal rosters. The talent was not strong this year due to some late defections and other players declining invitations because of summer school or long springs that ended in Omaha, meaning potential top draft picks like Stanford's Austin Wilson, North Carolina's Colin Moran, and South Carolina's Grayson Greiner weren't there.

I'm only discussing players I saw play on Friday and Saturday, so players already in Durham who didn't appear like N.C. State lefty Carlos Rodon, a potential No. 1 overall pick for 2014, or UCLA righty Adam Plutko -- are omitted or only mentioned in passing here.
